SPECIFICATION forming part of Letters Patent No. 374,904. dated December13, 1887.

Applicaiion filed November i3, 1886. Serial No. 218,769. (No model.)

To all whom, t may cgnc'c'n:

Be it known that I, HENRY MYERS, of Garnett, inthe county of Andersonand State of Kansas, have invented certain new and useful In'iprovementsin Windmills; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which- Figui-e1 isa perspective view ofmyimproved windmill. Fig. 2 is a vertical sectional view of the same, andFig. 3 is a horizontal sectional view.

Similar numerals of reference indicate corresponding parts in all thefigures.

My invention has relation to that class of windmills which revolve in ahorizontal plane,

land have vanes hinged at their inner edges and claimed.4

and placed obliqnely to the face of the frame to which they are hinged,having means for adjusting their angles to the direction of the wind;and it consists in the improved construction .and combination of partsof such a windmill, as hereinafter more fully described In theaccompanying drawings, the numeral 1 indicates the vertical post of theframe, which is formed at its upper end with a vertical bearing, 2, inwhich the vertical shaft is jonrnaled, the said shaft having its lowerend journaled or stepped in a suitable bearing or step, 4.

The shaft is formed near its upper end with a disk or spider, 5, fromwhich projects a conical frame consisting of downwardly and outwardlyinclined arms 7, connected by means of bars 8, in which slats 9 aresecured in radiating planes. The lower ends of the inclined arms areconnected by a circular rod, 10, and the vanes 11, which increase inwidth toward their lower ends, are hinged with their inner edges uponthe outer sides of these arms, at the rear edges of the same, foldinginto the spaces between the arms, covering the outer edges of theradiating slats. All the arms, or a number of the same, have rods 12secured to their outer sides by means of staples 13, and the upper endsof these rods are secured to the upper end of the vertical shaft, whilethe lower ends are provided with nuts 14, which bear against the undersides of eyes 15 at the lower ends of the arms, the said rods serving tobrace'the conical frame,having the nuts for the purpose of drawing theframe upward if it should sink upon the shaft. A collar, 1t', slidesupon the shaft below the spider of the conical frame, and is providedwith a circum- 6o ferential groove, 17, and with an annular iiange, 18,at its lower end. Arms 19 are pivoted with their inner ends in eyes 20in the periphery of this flange, and the outer ends of these armsproject through spaces between the radiating slats and are pivoted tothe inner sides of the vanes, having their outer ends inclined downward.A forked yoke, 2l, projects from a bar or rod, 22, sliding in verticalbearings upon the side of the upright post, 7o and this yoke tits withits arms into the groove in the sleeve, so that the sleeve may revolvewithin the arms of the yoke, and the sleeve at the same time may beraised or lowered by the rod and yoke. The lower end o f the sliding rodis pivoted to the upper end of a connecting-rod, 23, the lower end ofwhich is pivoted to the short arm of a lever, 24, pivoted upon the sideof the upright post, and

the long arm of this lever has a weight or 8e poise, 25, adjustablysliding upon it.

Long arms 26 project from the flange of the collar, projecting downwardand outward through longitudinal slots 27 in two dia- Ymetrically-opposite arms of the frame, and the lower ends of these armsor rods are bifurcated and formed with a series of trans verseperforations, 28, through which pass bolts 29, by means of whichthe'ends of the rods are pivoted to the ends of two bell-crank 9olevers, 30, fulcrumed at their bends upon the lower ends of the arms andhaving weights 3l upon their lower ends. v

It will now beseen that when the wind blows against the mill the windwill blow into the inner sides of the vanes, which will be forced tostand obliquely ont by the weights upon the bell-crank arms, allowingthe wind to revolve the wheel, and when the wheel revolves the weightsupon the-said bell-crank arms will be roo forced ont by the centrifugalforce, throwing the arms out and forcing the rods pivoted to their upperarms upward, raising the collar, which will cause the collar to drawupward upon the rods pivoted to it and fold the vanes against the edgesof the radiating slats, oiering less surface for the wind to actagainst. As the wheel slacks in speed, the weights will drop, drawingthe collar down and pushing the outer edges of the vanes outward, againoffering more surface to the wind, the said balls acting as governorsfor the speed' of the wheel.

The adjustably-sliding weight upon the lever will serve for the purposeof regulating the force with which it is necessary to slide the collar,and thus serve to regulate the speed of the revolutions of the wheel,the weight being adjusted farther out upon the lever-arm for the purposeof increasing the resistance to folding the vanes, while for the purposeof decreasing the resistance against the folding of the vanes the weightmay be adjusted nearer the fulcrum, the weight being raised as the vanesare folded.

By having the vanes decreasing in width toward their lower ends, and byhaving the frame wider at its lower portion than at its top, the forceof the wind upon the wheel Will be greater at its lower portion than atits top, preventing a too great pressure at the top of the shaft frombreaking the shaft or from tilting the frame and shaft, which may happenin wheels of this class, in which the Vpressure of the wind at the topof the wheel will be as great or greater than the force at the lower endof the wheel.

The wheel may be stopped by drawing down upon the lever having theadjustable weight, which will push the collar upward upon ythe shaft andclose the vanes into the spaces having the slats, giving the wheel asmooth conical surface.

The wind passing against theinclined inner faces of the vanes will beforced inward and against the radiating slats, causing the wind to exertits force against the slats, assisting in revolving the wheel, althoughthe slats may be dispensed with, if desired.

The entire wheel may be constructed at a comparatively low cost, as itcontains but few and simple elements, and will be very strong anddurable on account of its simplicity and on account of its shape, and itwill require no attention while in operation, as the governors willadjust the vanes in accordance with the force of the wind, it being onlynecessaryyto once adjust the weight upon the lever to be raised at acertain pressure, when the vanes will be folded whenever the windincreases to such a pressure and again be folded out when the pressuredecreases.

The shaft may extend to the bottom of the tower or supporting-'frame ofthe mill, or it may stop near the upper end of the same, and it may beprovided with any suitable means for conveying the rotary motion to thefoot of the tower or frame and with any suitable means and mechanism forconverting the rotary motion of the shaft into reciprocating or othermotion or for conveying the motion to a distant spot, the wheel being,however, principally intended for the purpose of pumping, and being thensuitably connected to a reci procating pump-rod.

Having thus described myinvent-ioml claim and desire to secure byLet-ters Patent of the United States- 1. In a wind-wheel, thecombination of a vertical shaft having a conical frame formed bydownwardly and outwardly inclined arms, vanes having their lower endswider than the upper ends and having their inner edges hinged to therear edges of the arms, a collar sliding upon the shaft and having anannular ange, downwardly-diverging rods pivoted to the fiange and to thevanes, rods pivoted to the flange and projecting through slots in thearms, and bell-cranks pivoted upon the lower ends of the arms andvhaving their upper arms pivoted to the rods projecting through theslots and having weights upon their lower arms, as and for the purposeshown and set forth.
